Abstract

Mammography is the primary imaging modality in the detection of breast cancer. However, the limited sensitivity and specificity of mammography in the radiographically dense or treated breast and in assessing response to chemotherapy has led to the development of adjunctive imaging techniques including Magnetic Resonance Imaging (MRI), Positron Emission Tomography (PET) and Scintimammography (SMM). The role of each of these specialized investigations is yet to be defined, but it has been established that they should not replace the use of conventional mammography and ultrasound, but be reserved as complementary techniques for resolving specificdefined problems. One of their main benefits appears to be improved loco-regional staging. In the current era of breast-conserving surgery accurate staging is mandatory so that inappropriate conservative surgery is not performed. Adjuvant imaging will help define the local extent of disease pre-operatively and thereby reduce local recurrence rates.
